1.	During radiography test, which region absorbs less radiation and transmits more?(a) Low and high density regions absorb and transmit same amount of radiation(b) High density region(c) Low density region(d) Low and high density regions adsorbI had been asked this question at a job interview.Query is from Testing topic in division Concrete Mix Design of Concrete Technology
Answer» Correct choice is (C) Low DENSITY region The explanation: This method uses short wavelength electromagnetic radiations such as X-RAYS and γ rays to detect internal defects. In this method the component to be tested is PLACED in path of radiations caused due to X-rays or γ rays.
